He explains Valkey's appeal through its native data structures, which reduce object-relational impedance mismatch, and describes production use cases including real-time fraud detection and IoT telemetry buffering. The conversation highlights Valkey 9.1's memory footprint optimizations and new database-level ACLs, which build on Valkey 9.0's logical database namespaces to enable role-based, per-database access permissions for safer multi-tenant consolidation. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What new security feature does Valkey 9.1 add for multi-tenant deployments? Valkey 9.1 introduces database-level Access Control Lists (ACLs), allowing role-based permissions to be scoped to specific logical databases within a cluster. This builds on Valkey 9.0's logical database namespaces, so a user can be restricted to querying only logical database 0 while another user is limited to database 10, replacing the prior all-or-nothing access model. _Teams consolidating multi-tenant workloads can track Valkey security updates like this on daily.dev._ ### How does Valkey typically get used alongside MySQL or PostgreSQL? Valkey is deployed almost exclusively as an in-memory caching companion to relational databases like MySQL, Postgres, or MongoDB rather than as a standalone database. Placing it as a caching layer offloads high-concurrency lookup patterns, reducing latency and deferring or eliminating the need for expensive vertical scaling of the primary relational database. _Developers weighing caching layer architectures can follow Valkey deployment patterns via daily.dev._ ### What memory efficiency improvements does Valkey 9.1 provide over previous versions? Valkey 9.1 delivers a purely software-driven reduction in memory footprint through continuous byte-level and memory-layout optimizations to internal structures. Because Valkey operations run fully in-memory and are constrained by memory capacity rather than CPU, a simple binary upgrade to 9.1 reclaims physical memory on existing infrastructure without requiring any code rewrites. _Infrastructure teams planning capacity can watch for memory-saving releases like this on daily.dev._ ## Similar posts on daily.dev - [Valkey just had a 17x year.
